If the buyer's country is under international sanctions, or if the buyer fails to provide a legitimate source of funds leading to the bank returning the payment, all transfer fees and exchange rate losses incurred during this period are to be borne entirely by the buyer.

Our legal red line is that the amounts on the China Customs declaration, export license, commercial invoice, and bank receipt must be consistent across all four documents. We firmly refuse to engage in the illegal act of issuing "false low-value invoices" to assist buyers in evading customs duties in the destination country.

We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.
